PROCESS FOR PRODUCING A DIFFRACTIVE ELEMENT, FOR USE IN PARTICULAR IN THE MANUFACTURE OF ARTIFICIAL OPTICAL LENSES, AND LENSES THUS OBTAINED

摘要

P The invention relates to a method for producing a diffractive element, characterized in that: - a matrix is impregnated in a cured polymer material by means of a liquid polymerizable composition comprising a monomer and a photo-initiator of polymerization under irradiation; - The material thus impregnated is subjected to local irradiation according to a network corresponding to the diffractive element to be formed, to harden said composition locally according to said network; - then the excess uncured solution is removed from the material. /P
